A totally awesome, hot chick who all the guys want to fuck, and all girls want to fuck like.

A female singer who kissed a girl and liked it and who thinks you're gay...

The art of listening or watching, memorising Katy Perry performances, videos and lyrics.

This could be in an obsessive fashion, or hardcore girl fan style.

This could also mean someone who is completely obsessed or deluded with Katy Perry in every way and is constantly needing to get their 'KP' fix, this is known as Katy Perrying.

the act of a girl kissing/making out with another girl.

The act of flashing and then thrusting your genitals in front of someone.

She is super inspirational. Her song firework really helped me through tough times when my ipod died. Her chorus for firework is so magical when she rhymes boom boom boom with moon moon moon, i die of happiness. Also you you you is rhymed with moon moon moon. Lastly, she tops it off with rhyming ah ah ah with ah ah ah.

Someone who gets a lot of nominations but never wins any of those.
